Question

2012 housing prices
sales price (thousands of $)
these two graphs show the same data. what is different about the two graphs?
the vertical scale
the horizontal scale
the width of intervals
the starting values of the intervals

Explanation:

The horizontal axis represents sales price intervals and the vertical axis represents frequency. Since only one graph is shown here but the question refers to two graphs, we assume we are comparing aspects of graph - making. The vertical scale is the set of values on the y - axis which could potentially be different between two graphs of the same data. The horizontal scale is about the sales price intervals which should be the same for the same data. The width of intervals and starting values of intervals are part of the horizontal scale and should be consistent for the same data representation.

Answer:

the vertical scale
